JEWELERS TOOL.

Specification of Letters Patent.

Patented Aug. 15, 1905.

Application iiled May 10, 1905. Serial Nie. 259.712-

To all whom it may concern,.-

Beit known thatI, ELZIE O. OHAMBERLIN, a citizen of the United States,residing at Denison,in the county of Crawford and State of Iowa,haveinvented a new and useful Jewelers Tool, of which the following isaspeciiication.

This invention relates to jewelers tools, and has for its object toprovide a novel form of pliers wherein the jaws are constructed andarranged for convenience in bending the prongs of a set-ring snuglyabout the set in a simple and effective manner with little or noliability of the set becoming broken. It is furthermore designed toarrange one of the jaws of the pliers for use as an anvil to support thering and to shape its jaws so as to enable the convenient turning of thering thereon to permit of the other jaw having access to the severalprongs of the ring and at the same time to prevent slipping of the ringupon the pliers.

ith these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention. t

In the accompanying drawings, Figure l is a perspective Viewillustrating one of the pli ers of the present invention in the act ofbending the top end of a prong down upon theset. Fig. 2 is detailperspective view of the lower or anvil jaw of the pliers. Fig. 3 is adetail plan view of said jaw. Fig. 4 is a perspective view ofthe upperjaw, which constitutes a die. Fig. 5 is an inverted plan view of theupper jaw. Fig. 6 is a detail cross-sectional View of the lower or anviljaw of the tool.

Like characters of reference designate corresponding parts in each andevery iigure of the drawings.

The present tool is made up of a pair of handle members 1 and 2, whichare crossed and provided at their points of crossing with the respectivebearing-eyes 3 and 4, that are pierced by a pivotal connection 5,whereby the plier members are pivotally connected in the usual manner.The lower jaw 6 of the upper handle member 1 projects beyond the upperjaw 7 and its upper face is provided With a lining 8 of suitable softmaterial, preferably brass. Each side of this lower jaw 6 1s providedwith a concaved seat 9, which extends into the inner or upper face ofthe jaw,

.tudinal groove there are transverse grooves 11, all of the groovesintersecting the respective outer edges of the jaw.

In using the tool or implement as shown in Fig. 1 the lower jaw or anvil6 is placed within a ring 12 at the under sideof the seat for the.reception of the set 13, which is formed by the usual prongs 14, afterwhich the handles are drawn together so as to press the jaw 7 againstthe side-of one of the prongs, so as to force the latter against theedge of the set, this operation being repeated until all of the prongshave been pressed against the set. It

will now be understood that the opposite sides of the lower anvil-jaw 6are provided with concaved seats leading to the inner or upper face ofthe jaw to permit turning of the ring upon the lower jaw to give theupper jaw access to all of the prongs, the face of the lower jaw beinglined with some soft metal to prevent scratching of the ring. After theprongs have been .forced laterally against the edge of the set the ringis brought into a position at substantially right angles to the lowerjaw and the tip ends of the prongs are bent down over the top of the setby means of the outer extremity of the upper jaw 7. In pressing down theextremities ofthe prongs each prong is received within the longitudinalgroove or channel 10 of the upper jaw and the entire tool removed orslid slightly toward the set, which ei'ectually upsets or bends theextremity of the prong without liability of the tool slip pingtherefrom. The side grooves or channels 11 are intended for the samepurpose where it is impossible to engage a prong with the groove 10.

From the foregoing description it will be understood that the tool ofthe present invention is exceedingly simple and effective for thepurpose designed and may be conveniently handled Without requiring anyparticular deof the jaw, and the other jaw terminating short of thefirst-mentioned jaw and formed t0 bear against the prongs of set-rings.

2. A tool of the character described comprising crossedpivotally-connected handles terminating in cooperating jaws, one of thejaws having its inner face concaved longitudinally and convexedtransversely, the opposite sides of the jaw being provided with concavedseats merging into the inner face of the jaw, and the other jaw beingterminated short of the first-mentioned jaw and formed for engagementwith the prongs of set-rings.

3. A tool of the character described comprising a pair of crossedpivotally-connected handle members terminating in jaws, one jaw beinglonger than the other and provided upon its inner face with a lining ofsoft metal, said inner face of the jaw being concaved longitudinally andconvexed transversely, opposite sides ofthe jaw being provided withconcavedseats merging into the inner face of the jaw,

and the other jaw being provided in its inner face with a longitudinalgroove intersecting its outer end, and transverse grooves located atopposite sides of the longitudinal groove and intersecting oppositesides of the jaw.

ln testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
